Discussion of a connection to Layton in this area began in 2008 while planning the City water tank project. As part of the project, a dirt access road was built off 1900 East up to the City’s new water tank at the top of the hill and is there currently. The amount of right of way was obtained, the underlying service infrastructure was placed, and the road was constructed in a way that preserved the option for a paved road in the same location sometime in the future.
The General Plan update in 2014 included paving this access road and connecting to Layton City, anticipating the road would function as a minor collector and disperse traffic demand as the City approaches build out. Additional in-depth studies need to be completed to determine the true viability and feasibility of the potential project.
The main discussions regarding this connection centered on additional ingress/egress options for City residents both for safety and convenience. Current limited options will continue to become more congested over time.
Safety – In case of emergency, the City has few options to evacuate the City. The Uintah fire a few years ago highlighted potential emergency situations as sections of the community required evacuation. If larger portions of the City require evacuation, greater distribution of traffic would provide increased safety.
Convenience – Residents looking for a quicker route to and from commercial options in Layton would be able to use this road rather than using US-89. Dispersing some traffic onto this road in and out of the City would also keep current roads less congested than they would be without it.
Inclusion in the General Plan does not guarantee that the road will be paved and does not make it a priority project to be completed soon. Additional study could declare the project impossible or funding may prove unattainable. However, inclusion allows the City to collect impact fees that could go toward the project (see question regarding who will pay for the road on this FAQ).
The City desires additional public comment regarding this specific alternative. The first General Plan draft survey in September 2019 asked about a connection to Layton generally, and many of the comments referenced South Bench Drive, which has been removed from the General Plan second draft. The City hopes to clarify if respondents felt the same regarding paving an extension of 1900 East up the hill to our water tank and potentially beyond. The question on the second draft is specific to whether the road should remain as a dirt access road in perpetuity or be paved sometime in the future.
It would be a two-lane road – one lane going each direction with an anticipated speed limit of 25 or 30 mph. The 2020 Draft General Plan contemplates the connection being a minor collector with traffic patterns similar to Deer Run Drive which carries the same designation.
Initial cost estimates (in today’s dollars) calculate the cost to be approximately $2,000,000. Other factors could potentially increase the cost to approximately $2,3000,000. See details below.
The Transportation Impact Fee Facilities Plan (IFFP) completed by Horrocks Engineers estimates the 1900 East project at $1,220,000. See Project #14 titled 1900 East Extension: Deer Run Drive to south Bench Drive (http://southwebercity.com/file/2017/07/2019-03-29-Transportation-IFFP_dated-2019-03-15-Horrocks-Engineers.pdf). The Project #14 estimate is to the connection point with the now discontinued South Bench Drive and not all the way to the Layton connection point.
In order to estimate the entire length of the 1900 East extension based off the IFFP unit costs and approximate length, City staff calculates:
- Total length of Project #14 is approximately 2,300 ft
- $1,220,000 / 2,300 ft = $530.44/ft
- Total length of 1900 East extension to Layton connection point is approximately 3,720 ft
- 3,720 ft * $530.44/ft = $1,973,236.80
City staff did not use IFFP calculations of the South Bench Drive project segment because the width of asphalt (50 ft) is different than the 1900 East project (36 ft).
The IFFP cost estimate includes:
- Clearing and grubbing
- Roadway Excavation
- Park strip
- Removal of asphalt HMA (asphalt)
- UTBC (road base)
- Curb and Gutter
- Sidewalk (6’ width)
- Drainage infrastructure (although the majority is already in)
- A “T” intersection at Deer Run/1900 East (not a roundabout)
- 15% Contingency, 10% Mobilization, 10% Preconstruction Engineering and 10% Construction Management (45% in addition to the actual construction costs)
The cost estimate does NOT include:
- Right of Way. There is approximately 3,720’ of 60’ wide ROW from 1900 East to the top of the hill already in the city’s name. If Layton puts their loop road where it is shown on the General Plan maps, then no additional ROW will be needed, other than minor adjustments for whatever the intersection configurations might be. If Layton moves their road south, then additional ROW would be needed, along with additional cost for the additional length of the road.
- Slope stabilizing / mitigation costs. The road is already graded and has been in use for approximately 10 years. It is unlikely that there would be additional stabilization measures needed. However, an updated geotechnical / geologic study would be needed to confirm this.
- Any scope changes. For example, if it was determined that the slope for a portion of the road is unacceptable (either through recommendations from a study or a decision from the staff or Council), then the cost is likely to go up. How much it would increase would be determined by how much of a change was required.
- Additional studies. As there has already been a geotechnical / geologic study done, an estimated updated report would be somewhere between $20K - $50K, depending on the depth of the study desired. A traffic and design evaluation study may be somewhere between $10K - $30K.
Staff feels that an estimation between $2,000,000 - $2,300,000 million is a close range based on the current concept plans. In order to be more accurate, project-specific preliminary design would need to be done.
The City would write the final check in the event the project happened. Funding could come from 3 potential sources: (1) transportation impact fees paid by developers, (2) grant funds from the State and County, and (3) City funds from Class C road money and sales tax.
Impact fees are paid by builders when they apply for a building permit. Impact fees can only be spent on transportation projects included in the General Plan and associated Capital Facilities and Impact Fee Facilities Plans. Including the 1900 East paved connection on the General Plan allows the City to utilize impact fees to fund the project. The Impact Fee Facility Plan identifies 37% of the project cost can be paid utilizing impact fees. Removing the connection from the General Plan means that if the project ever went forward then it cannot receive impact fee funding. Funding would have to come from other sources.
Class C road money is collected by the State of Utah from gasoline tax paid by consumers at the pump. A portion of the tax is distributed by the State to the City based upon the total miles of Class C roads within the City. All City-owned streets within South Weber are categorized as Class C.
State and County grants exist that are specific for road projects, though grant funding is never guaranteed. Grant eligibility for currently known grants requires the road to be functionally classified as a collector by the Utah Department of Transportation and Wasatch Front Regional Council upon request by the City. Classification as a collector is established by the nature and function of the road. For example, 1900 East and Deer Run currently function as collectors since both collect local, neighborhood traffic and connect them to higher capacity arterial roads. If 1900 East were to continue up the hill and eventually connect to roads in Layton, it would naturally function as a collector, regardless of width, inclusion of bike paths, and traffic counts, etc.
Unknown. The General Plan is a long-term planning tool that anticipates the future build-out of the City. Planning for the road through inclusion in the General Plan does not establish a specific timeline for construction.
Layton’s Transportation Master Plan shows a future extension of Fairfield Road to the north that would loop around to the east then south to connect with Grayhawk Drive or Church Street. The 1900 East extension would connect into the most northeastern part of this loop if/when it is constructed.
Yes. Money was spent for the design and construction of the dirt access road as part of the water tank project which included a slope study analysis, and in July 2010 an additional $5,649.00 was spent on a traffic impact study by A-Trans Engineering analyzing the potential impacts of a Layton connection. The study is posted below and at this LINK
Prior to any paving design and construction, two main areas would need to be studied – geotechnic conditions & traffic modeling. A geotechnical study addresses things such as slope stability, contamination, and pavement design. A traffic study would analyze things such as traffic counts, design elements such as road grade, and safety including weather conditions.
Considerable information is available that indicates general slope instability along many areas of the south bench of the City. Those studies do not specifically address what it would take for the current dirt road to be paved safely. Before a project is undertaken, those specific questions would need to be answered.
The City’s current Transportation Capital Facilities Plan based on the 2014 General Plan does not indicate 1900 East ever being widened, even if the access road were to be paved and connected to Layton City.
No. The City acknowledges that quality transportation networks are all about connection and that people typically communicate along the fastest route to their destination. Plans for Hill Air Force Base (HAFB) include a more robust east gate entrance. This road would provide connection near that entrance and while some traffic may use the road to access HAFB, the City is not working with HAFB to create this connection.
Yes. The idea has been considered. A decision would need to be made prior to beginning the actual project.
When the dirt access road extending off 1900 East up to the City's water tank was designed and constructed, the following studies informed the project:
- Geotechnical General Report
- Appendix A - Geologic Hazards Reconnaissance Report
- Appendix B - Wasatch Integrated Waste Site Analysis CPT Files and Plots
- Geotechnical Report Addendum 1 - Slope Stability
An additional study unrelated to the water tank project was completed in 2010 specifically addressing traffic impact of a potential connection to Layton by extending 1900 East:
